K-DRIFT: Unveiling New Imagery of the Hidden Universe
Jongwan Ko, Woowon Byun, Kwang-Il Seon +31
Low-surface-brightness (LSB) structures play a crucial role in understanding galaxy evolution by providing significant insights into galaxy interactions, the histories of mass asse…
Discovery of a large-scale H I plume in the NGC 7194 Group
Mina Pak, Junhyun Baek, Joon Hyeop Lee +5
We present the discovery of a new H I structure in the NGC 7194 group from the observations using the Karl G. Jansky Very Large Array. NGC 7194 group is a nearby (z ~ 0.027) small…
Performance Assessment of the KASI-Deep Rolling Imaging Fast-optics Telescope pathfinder
Woowon Byun, Jongwan Ko, Yunjong Kim +14
In a CDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures ar…
Variability and the size-luminosity relation of the intermediate mass AGN in NGC 4395
Hojin Cho, Jong-Hak Woo, Edmund Hodges-Kluck +31
We present the variability study of the lowest-luminosity Seyfert 1 galaxy NGC 4395 based on the photometric monitoring campaigns in 2017 and 2018. Using 22 ground-based and space…
Impact of Galaxy Mergers on the Colours of Cluster Galaxies
Sree Oh, Keunho Kim, Joon Hyeop Lee +9
We examine the ultraviolet and optical colours of 906 cluster galaxies from the KASI-Yonsei Deep Imaging Survey of Clusters (KYDISC). Galaxies have been divided into two categories…
Formation of Blue-cored Dwarf Early-type Galaxies in a Cluster Environment: a Kinematical Perspective
Jiwon Chung, Soo-Chang Rey, Eon-Chang Sung +3
The presence of blue cores in some dwarf early-type galaxies (dEs) in galaxy clusters suggests the scenario of late-type galaxy infall and subsequent transformation into red, quies…
